Matt Cooper:

When Obama pushed her aside tonight by starting her [sic] speech while she was barely into hers, there was something poignant about it. The Clinton voice has dominated politics for so long and tonight it was pushed aside, not only by Obama's speech but by his solid victory in Wisconsin, a state that could have been hers. Indeed, John McCain directed all of his fire tonight at Obama and ignored Clinton, even though a good Clinton jab would surely have fired up the conservatives he's been wooing so assiduously.
